The session also defines and examines the importance of equilibrium constant K and solubility product K sp, and the common ion effect. Since this equilibrium constant is the product of the ion concentrations (solubility products) we use subscript sp for this new value. After addition of Ca++ ions by adding Ca Cl2 the Ksp should remain constant so (OH')^2 will reduce from the earlier value and hence lesser volume of HCl is needed for Part-B. The solubility (S) of a mineral salt is the amount of the salt that is dissolved per unit volume.
